What is a TST file

TST files mostly belong to TestStand.

TST files are used to store test-related data. They often act as containers for test sequences, exam configurations, or automated test scripts. The files may be saved in plain text, compressed formats, or use specific text encodings.

Exam and Software Testing: Many tools, such as ExamView or other test applications, generate TST files to store test documents and configurations. These files can be encoded in formats like UTF-8 or UTF-16 (LE) and sometimes compressed with ZIP or GZIP.
Cable Testing: Some TST files are created by cable testing devices. For instance, files from Fluke Networks store cable test results. More details are available on the Fluke Networks website.
Test Sequencing: Certain software, including TestStand, uses TST files to manage test sequences and scripts for system or software validation. You can learn more on the NI TestStand page.
Special Text Uses: In a few cases, TST files serve to hold specific text content such as Turkish subtitles, processed with translation tools like TRADOS TagEditor.

FilExt.com note: If you do not have the original software, try opening the file with a text editor to see if the content is plain text. Matching the file with its original application is the best method to view and use the data.

How to open TST files

You need a suitable software like TestStand to open a TST file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your TST file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a TST file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert TST files:

RPG Toolkit (Tile File) by Christopher Matthews
The RPG Toolkit is a development system for creating Role Playing Games. The Standard Edition is free. A user has submitted this as the format for these files. A 6 bytes header: ** 2 bytes - magic 0x14 0x00 ** 2 bytes - number of tiles, little endian ** 2 bytes - subformat (0x01 0x00 or 0x02 0x00, maybe something else) In 0x01 0x00 format, what follows are tiles, 3072 bytes per tile. Each tile is always 32x32, with 3 bytes per tile (in order red, green, blue). The pixel data is transposed compared to the usual pixel formats, that is first are all the pixels of the first, column, then the second column etc. (in most formats it's first row, second row etc.). One color indicates "transparent", but it differs depending on the tileset, and is just a convention. Usually it's black or pink, but a few other colors are used sometimes. Information which color indicates transparent is not in the file. The 0x02 0x00 format differs however it's rather rare. Related links: RPG Toolkit Graphics Resources

TST file format:

The file format determines how the data is stored in the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. When there is a problem with a file, the first step to solving it is to determine the file format. In the following you will find our evaluation of the TST files:

TST is one of the most common file extensions and includes different formats for different programs. The two most common formats are as follows:

35% of all TST files are ExamView Test files. These are binary files, so they do not contain words or text. TST files are between 5 KB and 360 KB in size. The file type was developed 10 years ago and is still in use today. Certain words are almost always found in the files, such as FSCTST#W#06#00#x. These files can be linked to exam, unit, chapter, quiz, math, review, fall and midterm.
15% of all TST files are based on the well-known certificate file format. A digital certificate is a unique, digitally signed document which authoritatively identifies the identity of an individual or organization. Using public key cryptography, its authenticity can be verified to ensure that the software or website you are using is legitimate. These are binary files, so they do not contain words or text. The files are 3.2 KB to 3 KB in size, with a median of 3 KB.

All other TST files (50%) have no uniform format, frequently e.g. WinToets key, TestGen data, ZIP, GZIP, UTF-16 (LE), XML, Source, DOC, config, EXE, JSON, KCgbCLAmYb, ProgramInfo, Test, SQL, List, CATMAN, Cetr and UTStarcom. Files like these are sometimes linked to practice, grade, algebra, semester, intro or term. Just click the "Choose your .tst file to analyze" button on this page to find out what your TST file is.

How to solve problems with TST files

Associate the TST file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest TST file format. Search, therefore, e.g. on the manufacturer website after an available TestStand update.
To make sure that your TST file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
